2 Claims.

This application is a division of copending application, Serial No. 766,062, filed August 4, 1947, on Weather Indicator, now Patent No; 2,526,114.

This invention provides as a major object, a novel, portable or pocket device operative--upon manual adjustment or setting pursuant to a code indicia broadcast on the radio or' published in a newspaperto visually indicate a forecast of a weather condition, or an existing weather condition.

While the present device is especially designed as a weather indicator, its use is not so limited, and the device may be readily adapted to forecast or indicate other weather conditions, such as snow depth at a predetermined point, rain gauge readings at a given station, or the like.

Another important object of the present in; vention is to provide a weather condition indicaj tor of the type described whichcomprises a. novel disc and dial assembly; the front disc being; ported or windowed in a manner to register with prede termined parts of one dial whereby when the lat-'- ter is set with selected code indicia in register with one window another part of the dial registers thermometer-like at a point along an elongated window in the disc. 2

Still another object of the invention is to provide a temperature indicator which is designed for ease and economy of manufacture.

A still further object of the invention is to provide a practical and efiective temperature indicator, and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings:

Fig. 1 is a front elevation of the device.

Fig. 2 is a cross section on line 2-2 of Fig. 1.

Fig. 3 is an elevation of the smaller or temper; ature indicating dial, detached but showing "in dotted lines the relative positions of the cooper-r ating window and slot in the front disc of the device. 1

Referring now more particularly to the characters of reference on the drawings, the device is readily hand-supported, or of pocket size, being circular and relatively thin, comprising a front disc l and a rear disc 2 connected together at the adapted to register with arcuate windows I and 8 in the front disc I; the latter being cut away, as at 9, to permit of finger access to a portion In of the dial 4, whereby to rotate the latter to selective positions of adjustment, and in which positions of adjustment a number H of a concentric row thereof on the dial 4 registers through a port I2. Thus, by setting a predetermined weather code number in the port l2 corresponding to a forecast weather condition, the related weather condition as appearing in the row of weather indicia 6 will show through the windows I and 8.

The foregoing portion of the device is the subject of, and is claimed in, the hereinbefore identified parent application.

.The invention to which the instant divisional application is directed comprises a smaller dial l3 disposed, in. front of the larger dial 4, and. in position so that it does not obstruct either of the windows I or 8, or the viewing port l2. This is accomplished by pivoting the small dial l3 at an offset point, as at 14; the small dial being pivoted to the front disc i, whereas the large dial 4 is pivoted to the rear disc 2, as previously described.

On the side of the device opposite the cutaway 9 there is another cut-away l5 through which a portion l8 of the dial I3 is accessible for finger engagement to turn said dial.

Generally centrally thereof, and extending in a radial direction, the front disc I is formed with a slot l1 shaped to represent-for eXample-a thermometer; there being gradation markings or temperature readings on the face of the front disc I along said slot, as at 18.

On its face the small dial I3 is provided with a colored area [9, preferably red; the effective edge 20 of the area [9 extending transversely of the direction of rotation so that upon rotation of the small dial I3 the efiective edge 20 rides up or down relative to the slot IT, with a portion of said area I!) exposed through the slot I! below such edge. This provides the visual effect of a thermometer, and by setting the small dial I3 in a given position, a corresponding temperature reading is had along the slot l1.

On the side opposite the colored area IS the face of the small dial !3 includes an arcuate row 2! of indicia or letters concentric to the pivot 14; the front disc I having a viewing port 22 through which the letters of row 2! are adapted to register one at a time.

The letters of the row 2| are so disposed that each I thereof corresponds to a predetermined temperature setting of the small dial l3; i. e. a

predetermined temperature reading of the effective edge 20 of the red area l9 on the gradation markings or temperature readings 18.

It is proposed that in weather reports and forecasts, as broadcast or published, the existing or forecast temperature be given in one of the code letters, as in the row 2|. Thus, the user need only set the small dial I3 with the code letter reading in the viewing port 22. With such setting, the effective edge 20 automatically pro vides the existing or forecast temperature reading through the slot l1.

Instead of reading in terms of existing or forecast temperature, the slot and dial arrangement just described can be made to read in terms of snow depth for winter sports, or in rain gauge readings or the like for general weather information.

From the foregoing description it will be readily seen that therehas been produced such a device as substantially fulfills the objects of the invention, as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such;

detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described the invention, the following is claimed as new and useful, and upon,

which Letters Patent are desired:

1. An indicator device, for manual setting, comprising a face plate having an elongated slot therethrough, gradation marks on the front of the face plate along the slot, the face plate haV- ing a viewing port therethrough spaced from the' to the axis of rotation and adapted to successively register with said port; such indicia being so disposed that when a given one thereof is in register with the port, said edge of the colored area registers with a predetermined gradation mark along the slot.

2. A device for indicating weather conditions, such device comprising a face plate provided with an elongated slot in simulation of a thermometer tube, temperature indicating gradations imprinted on the face of the plate adjacent the transversely of the direction of rotation of the a row on the front of the back plate concentric disc and which intersects the slot with the rotation of the disc whereby such edge will visually move upwardly or downwardly along the slot with the revolution of the disc in one direction or the other, respectively, a plurality of indicia imprinted on the face of the disc concentric with the axis of the disc and arranged to be successively brought into register with the viewing port, such indicia being so disposed that when a given indicia is visible through the viewing port the said edge of the colored area will be disposed adjacent a predetermined one of said gradation marks.
